Dynamic partial buffer sharing scheme: proportional packet loss rate

In this paper, we propose a new packet loss control mechanism - dynamic partial buffer sharing scheme. With DPBS scheme, the thresholds are dynamically adjusted in run-time based on packet loss behavior. So that DPBS scheme avoids parameter-setting problem, and it can achieve desired relative packet loss ratio easily. In addition, DPBS scheme can achieve higher buffer utilization for its adaptation to network fluctuation. Simulation results show that DPBS has better performance than SPBS scheme under same traffic conditions.
